Just came across this snippet from Fowler's chapter on heathland courses in Hutchinson's 'Golf Greens and Greenkeeping' from 1906. Rather interesting...
"The Romans, I found, had been there some years ago, and they had designed some excellent bunkers, which I was first of all told by archaeologists were used as stables for their horses, but now higher authorities say that they were camp kitchens ; anyway, they come in capitally informing the best type of hazards. You may see the same deep hollows at Huntercombe, which, no doubt, was also a Roman camp."
